Which is solved by unlocking the drive and entering my macOS password. After going to the Disk Utility section the the Macintosh HD drive is greyed out: I tried the Apple recovery tool by holding the CMD+R at startup and downloading it. Even after setting the default boot option to macOS inside the Bootcamp utility and restarting the machine I am back in Windows. After restarting the machine and holding the Option key, 'Windows' is the only option I have. The problem is that I have lost the option to boot into macOS. Now Windows 10 is installed and working as expected, and so is the Boot Camp Utility software inside Windows. I don't recall exactly if it was a MBR/GPT or NTFS/FAT32 issue, but after formatting the drive I was able to proceed with the installation. The initial steps went smoothly until the actual windows installation where I was unable to install Windows on Boot Camp drive. Recently I tried installing Windows 10 using Boot Camp on my MacBook Pro.
